  1. 1. Performance Analysis of STTC-Based MIMO Under Cognitive RadioScenarios

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Sanjana Kankantee; Sai Praneeth Reddy Ganta; [2023]
    Keywords : Space-time trellis coding; MIMO; Cognitive radio; Performance; Bit error rate; Diversity; AWGN; Rayleigh fading; Detection; Spectrum.;

    Abstract : This thesis presents a comprehensive investigation into improving wireless transmission rates and reliability through the implementation of Space Time Trellis Codes(STTC). The study focuses on enhancing the coding gain, diversity gain, and flexible transmission capabilities, which are crucial for Error-Correcting Codes (ECC)in wireless communications. READ MORE

  3. 2. Adaptive Modulation Coding Scheme in Amplify and Forward Relay Networks

    University essay from Blekinge Tekniska Högskola/Institutionen för datavetenskap

    Author : Nirnay Reddy Nallavelli; Sushma Swaraj Chilupuri; [2022]
    Keywords : Adaptive Modulation; Modulation and Coding Schemes; Amplify and Forward; Signal to Noise Ratio; Nakagami-m Distribution.;

    Abstract : Wireless communications have become an essential part of our daily life. Despite the fact that wireless networks are simple to set up and deploy, the channel conditionsin wireless networks are susceptible to fading and attenuation, thereby reducing the transmission efficiency and reliability.

  4. 3. Link Adaptation in 5G Networks : Reinforcement Learning Framework based Approach

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Siva Satya Sri Ganesh Seeram; [2022]
    Keywords : Link Adaptation; OLLA; AMC; Reinforcement Learning; DDPG; BLER; Länkanpassning; OLLA; AMC; förstärkningsinlärning; DDPG; BLER;

    Abstract : Link Adaptation is a core feature introduced in gNodeB (gNB) for Adaptive Modulation and Coding (AMC) scheme in new generation cellular networks. The main purpose of this is to correct the estimated Signal-to-Interference-plus-Noise ratio (SINR) at gNB and select the appropriate Modulation and Coding Scheme (MCS) so the User Equipment (UE) can decode the data successfully.

  5. 4. Polar Codes for Biometric Identification Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yicheng Bao; [2022]
    Keywords : Biometrics; Polar codes; Identification systems; Convolutional neural networks; Autoencoder; Privacy preservation; Biometri; Polära koder; Identifieringssystem; Konvolutionella neurala nätverk; Autoencoder; Sekretessskydd;

    Abstract : Biometrics are widely used in identification systems, such as face, fingerprint, iris, etc. Polar code is the only code that can be strictly proved to achieve channel capacity, and it has been proved to be optimal for channel and source coding. READ MORE

  6. 5. Implementation and optimization of LDPC decoding algorithms tailored for Nvidia GPUs in 5G

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013); Karlstads universitet/Avdelningen för datavetenskap

    Author : Benjamin Salomonsson; [2022]
    Keywords : New Radio NR ; Shared Channel; Channel Coding; Low Density Parity-Check LDPC ; Min-Sum Algorithm MSA ; Graphics Processing Unit GPU ; Compute Unified Device Architecture CUDA ;

    Abstract : Low-Density Parity-Check (LDPC) codes are linear error-correcting codes used to establish reliable communication between units on a noisy transmission channel in mobile telecommunications. LDPC algorithms detect and recover altered or corrupted message bits using sparse parity-check matrices in order to decipher messages correctly. READ MORE
